SOHO OL-DESK.

Specification of Letters Patent.

Application filed March 3, 1909. Serial No. 481,116.

To all whom it may concern:

Be it known that I, Gnonon H. PARKER, a citizen of the United States,residing at Atlantic City, in the county of Atlantic and State of NewJersey, have invented certain new and useful Improvements in School-Desks, of which the following is a specification.

My invention relates to improvements in school desks, the object of theinvention being to provide an improved construction of desk mounting,which permits the desk to be adjusted vertically in accordance with thesize of the child occupying the same.

A further object is to provide improvements of this character, whichwill be so constructed that there will be practically no lateralwabbling or movement of the desk, and yet it may be adjusted verticallyat will.

lVith these and other objects in view, the invention consists in certainnovel features of construction, and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings, Figure 1, is a view partly in verticalsection illustrating my improvements. Fig. 2, is a view in section onthe line 22 of Fig. 1. Fig. 3, is a view in section on the line 33 ofFig. 1, and Fig. 4, is a view in section on the line 4-4 of Fig. 1.

1 represents a base adapted to be secured to the floor in any approvedmanner, and having an upwardly projecting rectangular column 2 inclosinga hollow post 3, which latter projects upwardly beyond the upper end ofcolumn 2, and is provided with longitudinal flanges or tongues a, toenter grooves 5 in the inner sides of a rectangular sleeve 6. The sleeveis constructed to nicely fit around post 3 and between the same and thecolumn 2, and will permit vertical adjustment of the sleeve, there ispractically no lateral movement owing to the close connection. The upperend of sleeve 6 supports and is secured to an ordinary school desk 7braced by a web bracket 8 connecting the desk with the sleeve as clearlyshown in Fig. 1.

9 represents a screw threaded rod, which is positioned within the hollowpost 8, and its threads engage screw threads in the upper portion 10 ofsaid post. The extreme upper portion of the rod is smooth, and madeangular as shown at 11 for the reception of a key 12 to turn the same,and a ring or collar 13 is secured to the rod by means of a screw 14,and is located between fixed rings 15 in sleeve 6, so that when said rodis turned in one direction, it will move the desk upward, and when movedin the opposite direction will draw the desk downward to adjust thelatter to the proper height.

Various slight changes might be made in the general form and arrangementof parts described without departing from my invention, and hence I donot restrict myself to the precise details set forth, but considermyself at liberty to make such changes and alterations as fairly fallwithin the spirit and scope of the claims.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. In a device of the character described, the combination with a base,a rectangular hollow column projecting upwardly on said base, arectangular post projecting upwardly on the base and locatedconcentrically within the column, tongues or flanges on opposite sidesof said post, a rectangular sleeve mounted between said post and columnand having longitudinal grooves receiving said tongues or flanges, ascrew threaded rod having screw threaded engagement with said post, ahead secured to said rod and fixed rings within said sleeve at oppositesides of said head, whereby when said rod is turned the sleeve will bemoved vertically relative to the post.

2. In a device of the character described, the combination with a base,of a vertical column projecting upwardly on the base, a post projectingupwardly on the base and located concentrically within the column,tongues or flanges on opposite sides of said post, a sleeve mountedbetween said post and column and having longitudinal grooves receivingsaid tongues or flanges, said post having a screw threaded socket, ascrew Patented Mar. 8, 1910.
